pytest-2.9.0

pytest is a mature Python testing tool with more than a 1100 tests against itself, passing on many different interpreters and platforms.

See below for the changes and see docs at:

As usual, you can upgrade from pypi via:

pip install -U pytest

2.9.0 (compared to 2.8.7)

New Features

  • New pytest.mark.skip mark, which unconditionally skips marked tests. Thanks @MichaelAquilina for the complete PR (#1040).
  • --doctest-glob may now be passed multiple times in the command-line. Thanks @jab and @nicoddemus for the PR.
  • New -rp and -rP reporting options give the summary and full output of passing tests, respectively. Thanks to @codewarrior0 for the PR.
  • pytest.mark.xfail now has a strict option which makes XPASS tests to fail the test suite, defaulting to False. There’s also a xfail_strict ini option that can be used to configure it project-wise. Thanks @rabbbit for the request and @nicoddemus for the PR (#1355).
  • Parser.addini now supports options of type bool. Thanks @nicoddemus for the PR.
  • New ALLOW_BYTES doctest option strips b prefixes from byte strings in doctest output (similar to ALLOW_UNICODE). Thanks @jaraco for the request and @nicoddemus for the PR (#1287).
  • give a hint on KeyboardInterrupt to use the –fulltrace option to show the errors, this fixes #1366. Thanks to @hpk42 for the report and @RonnyPfannschmidt for the PR.
  • catch IndexError exceptions when getting exception source location. This fixes pytest internal error for dynamically generated code (fixtures and tests) where source lines are fake by intention

Changes

  • Important: py.code has been merged into the pytest repository as pytest._code. This decision was made because py.code had very few uses outside pytest and the fact that it was in a different repository made it difficult to fix bugs on its code in a timely manner. The team hopes with this to be able to better refactor out and improve that code. This change shouldn’t affect users, but it is useful to let users aware if they encounter any strange behavior.

    Keep in mind that the code for pytest._code is private and experimental, so you definitely should not import it explicitly!

    Please note that the original py.code is still available in pylib.

  • pytest_enter_pdb now optionally receives the pytest config object. Thanks @nicoddemus for the PR.

  • Removed code and documentation for Python 2.5 or lower versions, including removal of the obsolete _pytest.assertion.oldinterpret module. Thanks @nicoddemus for the PR (#1226).

  • Comparisons now always show up in full when CI or BUILD_NUMBER is found in the environment, even when -vv isn’t used. Thanks @The-Compiler for the PR.

  • --lf and --ff now support long names: --last-failed and --failed-first respectively. Thanks @MichaelAquilina for the PR.

  • Added expected exceptions to pytest.raises fail message

  • Collection only displays progress (“collecting X items”) when in a terminal. This avoids cluttering the output when using --color=yes to obtain colors in CI integrations systems (#1397).

Bug Fixes

  • The -s and -c options should now work under xdist; Config.fromdictargs now represents its input much more faithfully. Thanks to @bukzor for the complete PR (#680).
  • Fix (#1290): support Python 3.5’s @ operator in assertion rewriting. Thanks @Shinkenjoe for report with test case and @tomviner for the PR.
  • Fix formatting utf-8 explanation messages (#1379). Thanks @biern for the PR.
  • Fix traceback style docs to describe all of the available options (auto/long/short/line/native/no), with auto being the default since v2.6. Thanks @hackebrot for the PR.
  • Fix (#1422): junit record_xml_property doesn’t allow multiple records with same name.
